These straws are not normal. EDDY+ SST EDDY+ SST EDIPLUS's charm isn't just as easy as drinking with a single action that makes the straw awake. Even when the straw is up, the valve will stay closed if you don't bite it, so even if you knock it down, the bottle will not spill out. Are you tired of leaking in your bag? Rest assured.
